Common Wiring Scenarios
One Light Fixture in a room
For some installations which require only a single emergency light in an area
with no regular lighting.
Two 3-Way Switches
When using two 3-way switches in a room to control the lighting from
two locations.
Dual Light Level Switching
For installations with dual light level controls. Can only be used when separate
ballasts are used for A leg and B leg. If using modern bi-level ballasts, contact
manufacturer for appropriate part number.
Wiring as shown will cause only “A” ballasts to operate as emergency xtures. If
all tubes are desired for emergency: use two ECS00-110’s or contact
the manufacturer.

What to do if...
ECS00-110 does not function properly on startup perform the following tests:
• Test Normal Operation: Ensure branch circuit breaker is connected and utility power is available. If GREEN LED is not illuminated, conrm wiring connections and
continuity to branch panels.
• Test Emergency Operation: Ensure emergency source is connected and RED LED is illuminated. Turn room switch to “OFF” position, and ensure that emergency
lights stay illuminated for at least 2.5 seconds. If emergency lights do not stay on for at least 2.5 seconds, conrm wiring connections and perform testing on
emergency panel and emergency power source.
No maintenance is required to keep the ECS00-110 functional. However, regular testing should be performed when the lamps or ballasts have been replaced or
when facility remodeling has taken place.
